A Detailed Look at the Koh Lanta: 4 Islands and Emerald Cave Tour

Getting Started: Pickup and Journey to the Pier

The experience kicks off with roundtrip hotel transfers, which many reviews highlight as smooth and punctual—an important factor when you’re on a tight schedule. The pickup usually starts in the morning, with guides ensuring everyone is comfortably on board before heading to the pier near Lanta Old Town.

The boat ride from the pier to the first island, Koh Chueak, lasts roughly 45 minutes, offering a chance to settle in, enjoy the sea breeze, and gear up for what’s to come. Some guests note that the boat rides can be the most challenging part, especially if the sea gets choppy. Several reviewers mention that waves can be rough, particularly inside the caves, so bringing waterproof bags and waterproof shoes is wise.

Koh Chueak: Snorkeling and Sea Caves

The first stop, Koh Chueak, is a diamond-shaped karst island famous for its sea caves and snorkeling spots. As you set out on your snorkel gear, you’ll quickly realize the allure: warm waters, a variety of fish, and colorful coral reefs. The guides often snorkel with guests, pointing out good areas and making sure everyone feels comfortable.

One reviewer, Michaela, shared that although the snorkeling was limited at some stops, the staff’s attentiveness and the chance to see fish up close made up for it. The caves themselves are a highlight—dark tunnels that require swimming through, sometimes in rough water, with guides like Lain ensuring safety and fun. Many find this part of the trip exhilarating—a little scary, but totally worth it.

Koh Mook and the Emerald Cave

Next, the tour takes you to Koh Mook, renowned for the spectacular Emerald Cave. You swim through a dark tunnel, which can be a bit intimidating due to the waves and darkness, but guides are experienced and help keep everyone safe. Once inside, you’re greeted by a green lagoon and a secluded beach—a true hidden gem.

Reviewers describe this experience as “amazing” and “exceptional,” with Sophie calling the cave visit “super glad I did this.” The cave’s dark tunnel, about 80 meters long, is only accessible by swimming through, so wearing appropriate gear (like waterproof shoes or fins) makes a difference. The lagoon’s vivid green water is like something out of a dream, and the beach behind it is perfect for relaxing after the swim.
